Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy base that mashes into the body of the dish.
- Hot milk or cream
- Adds moisture and richness, loosening the mash into a smooth texture.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
The step that matters
Let the potatoes dry completely after draining. Surplus water left on the potatoes dilutes the mash and makes it gluey or watery. Letting them steam dry concentrates the starch so the liquid added later is absorbed evenly.
